heafi receiver 1 supported 5 e swinging frame including cross bar Tat the The "sheaf receiver is; rotatably mounted? between arms 8 as by means of stub axles 11 projecting inwardly from, the swinging ends,

of the arms. The sheaf receiver comprises arcuate tread members '12 'formmgthe me] or portions ofcircles :wlththei'r ends connected configurationto each of 3 the tread members on one side.-' These treadmembersfare pro? 'tive-cross rails 14, and thesheaf receiver, as r vided with upper cross rails 14 and with I thus constructed, is jo l upon Stubv is eccentric with relation to the arcuate tread sheafreceiverthan-the upper and rear porr the inner endof the shaft 21 and parallel to p the tension of the spring.-

rear end toits forward end and is down Wardly inclined. It includes a central depression 18 with the sides of the pan curving laterally therefrom V and. then curved upwardlyfand slightly reverse," as shown at 19, to the upper edges of the pan. By this arrangement when the sheaves are deposited;

longitudinally within the pan with the butt ends forward, and above theicenter thereof;

the first sheaf will be positively correctly positioned within depression18,so$that the followingsheaves will 'be builtzup thereon to. form a usual frusto-conicalshock, having the base thereof atthe enlarged forward end of the pan.

After the 'sheaveshave been deposited in the receiver pan, and when: the latter is rotated in order toupend theshock, pressure isexerted upon the upper side of the sheaves. within the pan sov as to press the same intothe form of ashock and retain theshock in position until the rotation of the sheafreceiverhas upended it from the the upper edgeotthe' pangso astooverlie oneside thereof. The spring 23 upon the shaft 21 tendsto swingthe rear end of the crank 22' downwardly, and al-u-g 2% projecting froin the shaft 21 and resting upon=the cam 20 causes the downward swing of the crank 22 to be restricted by the cam against A- sleeve25 is journal-led upon the crank 22 and is provided at its rear end with a laterally projecting pressure arm 26'. The sleeve isacted upon by a C0ll spring 27 i which tends toelevate the-presure arm to an upright-position,"in which it'willgnot' obstruct the depositing of the sheaves within the pan, and this actionof the spring-is controlled by means of a rcarwardly proje'cting tail piece 28 which engages the edge of thereceiving pan. hen the crank end 22 is swung downwardly, thetail piece will be swept down in contact with the inner-face of the pan, and the space between the-sleeve and the; pan beingrestricted the tail piece will be trailed behind the sleevathereby iinf parting rotation to-the sleeve and causing the.

pressure arm 26 to be swung downwardly against the sheaves within the-pan. The downward or inner swing of theorank end 22will be occasioned by thetension of the spring 23 und'erthe control of the cam'20 H which acts uponthe-lug 24. This rocking of the 'sleeve 25 against" spring tension, and

the. resultant down swing of the pressure arm 26 across the pan,v take place in sequence, so that as the pan 18 being tilted to deposit theshock upon the ground the pressiu earm Will be moved downwardly and rearwardly with respect to the main frame of the machine, thereby exerting a downward and rearward pressure against the body of theshock as the same is being butted upon the ground. The rearward component ofmovement of the arm 26 atthe time of delivery of the shock is substantially equal to the forward advance of the machine as a whole, so that the shock? will be steadied at the instant it strikes the ground and its acquired momentum will be resisted in the manner stated, so as to overcome: the: tendncy of the shock to topple forward during the return movement of the pan over the top of the shock.

The mechanism for normally retaining arms 8. in their upwardly swung position inoludes notches 30 provided in uprights 10 and latch members 31 pivoted to arms 8, zmdprovided with rollers 31 adapted toengage said notches to. prevent downward swing of said arms or to be released therefrom, sothat the arms and the sheaf receiver carried thereby will be loweredby gravity. The latches 31 are operated by connecting rods 32 extending to the front of the machine and preferably adjust-ably connected by means of nuts 33 to arms 34- depending from a iotatabl'e cross rod This rod is extended beyond the side of the machine and is provided with a suitable opera-ting connection 36 whereby it maybe oscillated by the operator. The latching members are normally held inengaging' position by means of springs 37 connected at their respective endsto arms 8 and to the arms 34, so as toyieldably moveconnecting rods 32 in a direction to cause engagement of the latch mechanism. It will be understood that when the operator swings rod 35 in. the opposite direction, that the latch mechanism is released so that the arms 8 and the sheaf receiver carried thereby are swung down- Vhenthe sheaf receiver is thus lowered, the forward lower endsof tread members 12 engage the ground and the continued forward movement of the shocker will cause the sheaf receiver to berotated. upon its axis provided by: stub shafts 11 as the tread members continue to engage the ground.

The position of the mechanism, when the shoutreceiver is first released so as todrop to the ground, is shown in Fig. i, and the position of the sheaf receiver, when it has been rotated so as to upend the sheaf recciver and thereby release the shock therefrom, is shown in Fig. 5. It will be noted that as the sheaf receiver swings from the position shown in Fig. 4 to the position the ground in order to firmly-form the same.

For this purpose, shaft 21 isprovided with asse sor shown 'inFig. 5, that the lug Q L moVing along cam surface 20, will permit gradually,

increasing downward swing of the rear end} ofcrank 22, and as a consequence thepressurearm 26 will exerta gradually increas ing pressure against the shock within the receiver pan.

When the ended, as shown in Fig. 5, the pressure arm 26 1s arranged to exert avfinal increased pressure against the shock as 1t. 1s placed upon an arm projecting laterally therefrom and adapted toengage lugs 41 depending from one of arms 8. The rotation of the sheaf receiver will thus cause shaft 21 to be further rotated by the abutment of arm 40 against lugs 41, and crank 22wi1l there'- by be given a final increment of compressive movement, which'with the pan in tilted -po-" sition Wlll be in a rearward Clll'GCtlOIl' as regards the line of advance of the machine,

thereby forcing the pressure arm" 26 more firmly against the butted shock to restrain its tendencyto topple over. When the armAO passes beyond the lugs 41, the lug 24 will already have passed under and become disengaged from the camQO, and further rotation of the shaft will then .be prevented by the contactof the lug 24 against a stop 2 beneath the same, as shown in-Fig. 9. As the pressure of the rod 26 is released by the discharge of thes'hock and the concur- 1-ent advance of the machine, thecontinued' rotation of the sheaf receiver over the top of the deposited shock'to'its normal or receiving=positionwill cause the lug 24 to engage the rear or under portion ofthe cam 20 which 18 so confi ured as to swin uthe' crank 22 unwardl a ainst the tension of the spring 23, and thereby permit the arm 26 to swing upwardly undertlieinfiuence of l the spring 27 as thetail piec e 28 slides over t-he'edge of the pan. The'arm 26 thus moves out of the Way of the sheaves to be subs'e--- quently deposited in the receiving pan.

r It will also be noted thatthe eccentric configuration of thetread-members causes the bearings for thepanto be lifted to. their highest degree at the time when the pan is f in overturned position and somersaulting forward over the top of the deposited shock,

and this arrangement affords the'necessaryclearance'betweenthe shock and the pan to prevent a toppling over of the buttedshock by the contact of the pan on its re The arrangement is also turn movement. such'asto cause the arms 8 to be swung upwardly by the acquired momentum'of the pan as itreturnsto normal position, so that when the sheaf'receivcr has completed its .rotation'and'is again in position to receive sheaves, the arm 8 will'be fully raised and sheaf receiver'reaches the point in its rotation where. the shock will be.up-'

again lield in such position by the latch mechanism. A stop 42 depends from the superstructure 43ofthe shocker frame in alinement with one of the tread members12, so that as the sheaf receiver completes its .rotation the stop will engage the tread member to prevent further rotation until the sheafreceiver is again loweredby operation ofthe latch-mechanism, the relation of these parts beingsuch that the lowering of ,the sheaf: receiver brings the axis of the pan'sufliciently fariorwardto permit clear:

ance oft-he stopswhen'the pan is rotated.

The means for feeding the sheaves to the receiving pan lengthwise of' the latter, in-

I cludes a downwardlyinclined chutewla care ried by the superstructure4t3 above the .ro-

tating sheaf receiver and extending from the ning overthe same. The upper sprocket is preferably a drive sprocket and maybe acrunning over th'e'same lhis chainis' preferably driven by a sprocket wheel 52 mounthand flOntwheel Of the shocker. The conveyor-preferably includes chains 53 at therespective-sides ofthesame and running in channel members F54. Pivotally mounted rods 55 connect the respective;

ed upon. thelaxle' of the nonswivelling left chains and are provided with laterally projecting'rtines 56 which are adapted to be side of the machine, which is adjacent the l tuated byua bevel. gearS meshing witha V 'bevelgear 49 upon the sprocket and rotated by a sprocket wheel 50 havinga chain 51 swung outwardly so as toengage beneath a sheaf andiele'vate the same along the jcon- I veyor. I The rods 55areprovided with laterallygprojectinglugs 57 at right angles to [tines 56, and so positioned as to abut against channelmember 54 during the upward flight of theconveyor, and'thereby-retainrods 5 5 against rotation and tines 5.6, inoutwardly swung position for supporting the sheaves. As the conveyor passes over the upper sprocket, the sheaves aredropped into chute 44: and will roll downthe same to a position I disengage the tines 56 from the sheaves as the lattersmove into chute 44, a projection 59 is preferablyformedat the side of the conveyorin suchposition' as to engage tines 56, so as to swing the rods and thereby movethe 'tines away; from the sheaves; This above the'centerof the receiving. pan and lengthwise thereof. Inorder to positively is formed between the end of thechute, and

tines 60 spaced therefrom and mounted upon a' pivotally supported cross rod 61. The tines 60 are normally swung upwardly to the position shown in Fig. 1 so as to engage the sheaves as they pass beyond the end of chute 44:, and when in such position the dropping of a sheaf to the receiving pan is prevented. The tines engaging a sheaf will also correctly position the same with relation to the sheaf receiving pan, so that the sheaf is exactly above the central depression of the pan and parallel thereto. Vhen the receiving pan is in its normal position to receive the sheaves, the weight of a sheaf against tines 60 will rotate rod 61 against the tension of yieldably retaining means in order to permit the passage of the sheaf, which will thus be dropped horizontally into the receiving pan and exactly parallel to its length.

The yieldable retaining means preferably consist of an arm 62projecting upwardly from pivot rod 61 and connected by a spring 63 to the superstructure 43. During the tiine that the sheaf receiver is rotatin in upon one of the traction members, but as soon as the sheaf receiver starts to rotate and-the lug 67 passes from beneath arm 66, the latter will swing upon its p vot so as to bring its inner end into alinement with arm 65, and thereby prevent swinging. of the same and consequent rotation of rod 61 and the downward swinging of tines into position for releasing the sheaves;

In practice the sheaves supplied 'to the shocker will be of somewhat different le ths' w I I b e at different times, due to the variations in the height of the standing gram, and the sheaf receiving and upending mechanism is adjustable treads extending circiunferentiah ly thereof and adjust-able radially toward and away from the principal tread members. For this purpose the, treads are shown as comprising sections 7()7O carrying bracket arms 71 and hinged at 72. The opposite ends of the tread sections are heldby brackets 71. The various brackets are adjustably secured to the tread members by bolts received through any one of a plurality of bolt openings 7 2 provided along the lengths of the brackets.

Asa shock is upended from the sheaf receiver, it is desirable that the base thereof be spread so as to form a firm support upon the ground, and for this purpose a plurality of tines F3 depend from the main frame of the machine in front of the rotatable sheaf receiver. I The tines are provided with rearwardly projecting lower ends 74 forming angles which are so positioned as to receive the en-dsof the sheaves forming the front portion of the shock as it is upended. As a consequence, as the shocker continues its forward, movement the tines will pull the forward portion of the base of the shock forwardly and thereby spread the same. In practice the tines 7 3 are supported in spaced relation across the front of the machine so as to engage the base of a shock throughout the width thereof, and are so shaped as to engage the various portions of the base of the shock which are in alinement with the respective tines. "The tines are preferably pivotally adjustably mounted upon the frame of the machine so as to be swung up or down a greater or less distance for engagement beneath the base of the shock, and thereby vary the degree to which said base is spread, as may be found desirable.

it will be noted that the construction as thus described, provides convenient means for discharging sheaves to a receiving pan which is so constructed as to form the same into a shock, and that the receiving pan is so arranged that when released it will be lowered in order to b ing tread members into en agement with the ground and thereby completely rotate the sheaf receiver, and as same. It will be further noted that the eccentric arrangement of the tread members Wlll cause the sheaf receiver to be againraised to its original position as the rotation of the same is completed, in order that sheaves may again be discharged to the receiving pan for come inoperative and which is lightin draft and simple in operation.

The pressure arm is actuated in such a manner as to combine within itself the functions of compressing the shock in order to compact it prior to its deposit on the ground, of assisting in forcing the shock down upon the ground by reason of its arcuate movement in a downward direction during the a consequence upend the shock from the its return movement.

rotation offthe crank section in a direction which 1sdownward and rearward'with re-' spect to the ground surface.v

lated with due regard to the height of the grain and ground'conditions,so that the pan may always be adjusted to asufiicient height to clear the stop of the deposited shock. The

formation ofthe panwith the central chan- I nel or depression insures the building up of a symmetrical shock, since the first sheaf,

being centrally deposited,assists in causing the remaining sheaves to take positions in the pan in parallel/relation to oneanother.
